[−][src]Struct tower_web::util::buf_stream::size_hint::SizeHint

pub struct SizeHint { /* fields omitted */ }

A BufStream size hint

The default implementation returns:

0 for available
0 for lower
None for upper.

Methods

`impl SizeHint`
[src]

`pub fn available(&self) -> usize`
[src]

Returns the lower bound of the amount of data that can be read from the BufStream without NotReady being returned.

It is possible that more data is currently available.

`pub fn lower(&self) -> usize`
[src]

Returns the lower bound of data that the BufStream will yield before completing.

`pub fn upper(&self) -> Option<usize>`
[src]

Returns the upper bound of data the BufStream will yield before completing, or None if the value is unknown.
